What is the standard width of a motor vehicle lane in meters?

For a two-way four-lane road, it is 2x7.5 meters; for a two-way six-lane road, it is 2x11.25 meters; for a two-way eight-lane road, it is 2x15 meters. According to road conditions and traffic needs: Roads are divided into motor vehicle lanes, non-motor vehicle lanes, and pedestrian walkways, with motor vehicles, non-motor vehicles, and pedestrians traveling in their respective lanes. If the road is not divided into motor vehicle lanes, non-motor vehicle lanes, and pedestrian walkways, motor vehicles travel in the middle of the road, while non-motor vehicles and pedestrians travel on both sides. When motor vehicles are driven on the road: They must not exceed the maximum speed indicated by speed limit signs. On road sections without speed limit signs, a safe speed should be maintained. When driving at night or on sections prone to danger, or under weather conditions such as sandstorms, hail, rain, snow, fog, or icy roads, the driving speed should be reduced.

What does driving dual vehicles mean?

Driving dual vehicles refers to traffic restrictions where odd-numbered vehicles are allowed on odd-numbered days and even-numbered vehicles on even-numbered days. Odd-even traffic restrictions: The odd-even traffic restriction system is a traffic management measure introduced to alleviate urban traffic congestion. During the 2007 Beijing Olympic test events, Beijing first implemented the odd-even traffic restriction policy. On odd-numbered dates, only private vehicles with license plates ending in an odd number are permitted on the road, while on even-numbered dates, only those ending in an even number are allowed. Last-digit traffic restrictions: The last-digit traffic restriction system is another measure developed to ease urban traffic pressure, which has proven effective in reducing traffic congestion after implementation. During the 2008 Beijing Olympic test events, Beijing adopted the odd-even traffic restriction policy. On odd-numbered dates, only private vehicles with license plates ending in an odd number can be driven, and on even-numbered dates, only those ending in an even number are permitted.

Can You Make a U-Turn When Turning Left?

You can make a U-turn when turning left. Rules for U-turns at traffic lights: At intersections with U-turn traffic lights or road signs indicating U-turns, you can make a U-turn after ensuring safety. At intersections without a U-turn light but with a left-turn light, U-turns are allowed. Drivers can use the left-turn lane to make a U-turn at the central median or when approaching the intersection, provided it does not affect normal traffic flow. Yellow grid areas: Although stopping is prohibited in yellow grid areas, if the traffic light ahead is red, vehicles behind should reasonably avoid stopping in this area. A U-turn can be completed at the central median barrier. Crosswalk areas: U-turns are not allowed on crosswalks or pedestrian crossings. You can make a U-turn after crossing the crosswalk when the light is green, but never make a U-turn directly on the crosswalk.

How long is the lifespan of an electric car battery before it needs replacement?

Electric car batteries generally have a lifespan of around ten years. Precautions for using electric car batteries: After parking, avoid prolonged use of electrical equipment. The service life of a battery is typically about 3 years. For vehicle battery maintenance, try not to play music after turning off the engine. If the vehicle is parked for an extended period, disconnect the negative terminal of the battery to extend its lifespan. Automobile warranty legal provisions: On October 1, 2013, the national "Regulations on the Repair, Replacement, and Return of Household Automobiles" was officially implemented. Article 17 of the regulations states that the warranty period for household automobiles shall not be less than 3 years or 60,000 kilometers, whichever comes first. The three-guarantee validity period for household automobiles shall not be less than 2 years or 50,000 kilometers, whichever comes first.

What causes the green light to flash without switching to gas in a gasoline-to-gas conversion?

If the green light flashes without switching to gas in a gasoline-to-gas conversion, it might be due to a stuck fuel pump or a malfunctioning fuel pump, which can cause sudden fuel supply interruption and engine stalling. Introduction to Gasoline-to-Gas Conversion: It involves installing a natural gas system in a conventional gasoline-powered vehicle, allowing it to switch between gasoline and natural gas, effectively making it a dual-fuel vehicle. When the coolant temperature exceeds 60 degrees Celsius, the system can switch between natural gas and gasoline. When the natural gas is nearly depleted, the system can also be forced to switch back to gasoline mode. Pros and Cons of Gasoline-to-Gas Conversion: The advantages include cleaner and more efficient combustion, reduced carbon buildup, superior anti-knock performance, and no dilution of engine oil, thereby extending the lifespan of internal engine components. The drawbacks include a potential power loss of 10% to 20% in some converted vehicles, increased vehicle weight, and slightly reduced performance compared to running on gasoline.

What is the application scope of 85w-90 gear oil?

85w-90 gear oil is suitable for manual transmission vehicles. Working conditions of gear oil: The contact area between gears is very small, basically line contact, and during movement there is both rolling friction and sliding friction. Therefore, the working conditions of gear oil are quite different from other lubricants. Due to the small contact area between gears, the pressure they bear is very high. The tooth surface pressure of some heavy machinery reducer gears reaches 400-1000MPa, and the operating conditions of hypoid gears in automotive transmission systems are even more demanding with heavier loads. The pressure at the contact points can be as high as 1000-4000MPa. Under such high pressure, the lubricating oil is easily squeezed out from between the teeth, which can easily cause scratches and wear on the tooth surfaces. Therefore, gear oil must have the performance to keep the tooth surfaces in a state of boundary lubrication and elastohydrodynamic lubrication under high loads. Functions of gear oil: Lubricate the transmission system, reduce wear on gears and moving parts, ensure normal operation of the transmission system, and extend service life. Reduce friction and transmission losses in gear transmissions, improving mechanical efficiency. Cool transmission components. During gear transmission, a large amount of heat is generated due to tooth surface contact friction. If not dissipated in time, it can cause
